I COMBINED LISTER l-LOWAND PLANT E R.

SPECIFICATION forming part of Letters To all whom it may concern-.- I Be it known that I, EDWARD P. LYNCH, of Davenport, in the county of Scott and State of Iowa, have invented certain Improvements in Combined ListerPlows and Planters, of which the following is a specification.

This invention relates to that class of implement-s in which a furrow is formed by a double mold board plow, a second furrow formed in its center by a subsoiling device, the seed delivered behind the subsoiler, and the seed finally covered by the scrapers; and the invention consists in various improvements having reference to the manner of constructing and uniting theva'rious parts. 1

In the accompanying drawings Figure 1 is a perspective view of my improved implement. Fig. 2 is a sideelevation of the same with various parts in section. Fig. 3 is a side elevation showing one of the covering devices.

Fig. 4 is a-rear elevation showing the covering devices. Fig. 5 is a view of the frog.

Referring'to the drawings, A represents the beam; B, the casting, commonly denominated the frog, firmly secured to the lower end of the beam; G,a right andleft mold-board,commonly known as a double mold board, bolted, together with the usual share, firmly to 'the'front of the frog'B, the subsoiling device having its standard firmly secured in the frog behind the beam, as hereinafter de-- scribed; E E, the two divergent handles hav ing their forward ends rigidly bolted to the sides of the frog B; F, the seeder-frame con sisting of two bars arranged side by side at suitable distances apart and connected at their forward ends to the frog by a horizontal pivot 5 that their rear ends may rise and fall with freedom.

G is an opener rigidly secured to the frame F in rear of the subsoiler for the purpose of opening a furrow for the seed. The opener is commonly constructed with a vertical seed spout or passage g in its rear end to conduct the seed from the distributing devices above to the furrow. v

' H is a seed box or hopper, provided at its base with seed-distributing mechanism of any suitable character adapted to operate by a horizontal shaft. This box is sustained upon a base plate or arm I, which is in turn conpivot t', preferably, to the gravitating frame F. Each is permitted a vertical motio-nindependent of the other.

erated by a transverse shaft J, passing through The entire seeding meclr anism is sustained and the feeding devices opnect-ed at its forward end by a horizontal the arms I and provided at its ends with one or two ground-Wheels K K.

L L represent two shovels or co-operating devices attached to the side bars of the frame F in the rear of the runner for the purpose of turning the soil inward over the seed.

In order to insure the proper action of the runner and the covering devices, I prefer to lock them at fixed heights in relation to the subsoiler and mold-board. To this end I pivot to the rear end of the frame 'F an -upright bar M, the upper end of whichis notched and passed through a plate m, bolted to the crossbar m, which connects the plow-handles E E. The plate on is adapted at the rear edge to enter the notch and hold the bar M, and is provided at the front with a spring 071 to maintain the engagement. By shoving the bar forward it may be disengaged, so as to admit of its moving vertically to change the height of the runner and subsoiler.

It is to be observed that, although the opener and subsoiler are locked in position, the seed mechanism and its wheel are permitted a free vertical motion, so that the wheels are certain to travel at alltimes upon the bottom of the furrow, and thus insure the uniform delivery of the seed.

The frog B is cast complete in one piece, and serves as a support for and connection between the beam, the mold-board, the share, the handles, the subsoiler, and the rear frame. It is fashioned, as shown at Fig. 5, with its front face adapted to receive the mold-board and share, with avertical socket b to receive the end of the beam, with an open slot 19 at the rear to receive the standard or shank of the subsoiler, and witlrbearings ff for the edges of the standard. The transverse belt 1) passes through the'rear open edge of the frog, and serves to contract the same laterally upon the subsoiler standard, holding it firmly in position to permit it to be adjusted vertically-when they are released.

' In' order that the angle or inclination of the clination of the shovel.

ler may he ch ng d a will, th ot mush which the uppe bc t 12 pa e e elongated in a fore-and-aft direction, and a wedge b inserted between the standard and the rear edge of the beam, as shown in Fig. 2. By raising the lower end of the wedge and by shifting the bolt b in the slots, the upper end of the standard may be moved forward and backward and locked firmly in the desired position.

The covering-blades may be made of the form and attached to the frame F in the manner shown in Figs. 1, 3 and 5. In these figures each shovel is connected by a foreand-aft pivot-bolt 11, passing through a horizonta slot in a casting i SQ that th pa nt of h shovel may be thrown to th igh Drlcft, as d s ed- The sh v l i also s o ed V9331 callyt'o adm t (If ts being is an l wered inen the n vctrho he s ies is n tu n on ected t the bea y a tr ns erse pi and p ovid d t the forwa d end wi h We or more holes 2' to receive a brealgc-pin or a fastening bolt. This arrangement admits f th as ing be n changed in po t on on the beam to vary the pitch or forward in- The c ve i de v ces may h othe wise formed nd at ache if preferred.

Hav ng thus de cr bed my hivent ch, wha I claim is.-

1. In a cqmbined lister and planter, the

ombi ation of he free. w th the mel -hoa shar nd e b ci e a hed. he h ged frame F, haying the opener and covering devices attached, the hinged gravitating frame Pr v ed ith a s e n me ani m, and the frame-sustaining and seederoperating shaft J, provided with one or more furrow- Wheels.

2. The herein-described frog B, having the surface to receive the mold-board and share, and the vertical openings to receive the beam and the subsoiler-standard.

3. In combination with the beam, the frog embracing its end and sustaining the moldboard and share, the subsoiler-standard in serted through the rear side of the frog, and the transverse bolt contracting the frog to hold the standard.

4. In combination with the beam, the frog embracing its end and provided with the foreand-aft slots, the subsoiler-standard passing through the frog in rear of the beam, the transverse adjustable bolt, and the wedge, whereby the subsoiler is held adjustably in position.

5. In combination with the beam,the moldboard. and share, the subsoiler, and handles, the single casting or frog, to which all of sa d membe ar nit an by whi they are h l n runner tions 6. The mold-board plow provided With an les, n comb na on with a f am hinged thereto nd pmvided wi h fu row op nin nd over ng de ces, a ar xtend n Qt e handles for vertically adjusting and locking said frame to regulate the depth of planting, a hinged gravitating frame or bar with a seedrdis r bu r ther n, n su a nin s a f e gravitat g frame, p o ded a s end ith 9116 r wo h s ra e ng at the sides of the furrow.

7. The beam, the frog inclosing its end, the moldbo ard and subsoiler secured to the frog, the frame F, hinged to the frogand provided with the opener, the seederrcarrying frame I, hinged to frame F, and the shaft and sustainingrwheels applied to frame I, said elements combined substantially as described and shown.

In testimony whereof I have hereunto set my hand, this 6th day of June, 1889, in the presence of two attesting Witnesses.
